. No. 865,49. Specification To all wiiom it mag concern:

Be it known that I, GEORGE M.. GRAHAM, a citizen of the United States-ofAmerica, and aresident of Chif" cago, in the county of Cook'and State ofIllinois, have invented certain new and useful Improvements in Fi'ttingsfor Metal Reinforce Constructions, of which thefollowingisaspecification. I

This invention relates to fittmgsfor connecting-together the tubularcolumns, girders .etc. of metal re-j inforce frames of concrete buildin'etc." and more es pecially the type of such frames and frame parts,which constitute'the subject matteroi my companion applications forLetters Patent Serial Numbers349,682 and 349,684 filed of evendateherewithJ; And the present improvement has for its object to providea simple and efficient structural formation and combination'of part s"whereby an easy connection is had, and which atthe same time provides asubstantial attachment of the parts with ample strength to resistallordinarystrains', allas will hereinafter morefully appear. In theaccompanying drawings :Figure. 1, is a plan view illustrating thepresent invention applied to' a cross fitting. Fig. 2, is a sideelevation of the same.

Fig. 3, is a horizontalsection of the preferred forrn of the same.

Fig. 4, is a similar View of a modified form I .of the same. Fig. 5, is..'plan view illustrating the invention applied to a. tee fitting. Fig.6, is a similar view illustrating the invention applied to an ellfitting. Fig. 7 is a plan view illustrating the invention applied to aduplex or multiple ell fitting. Fig. 8, is a side elevation of the same.Fig. 9, is'a plan view illustrating the present invention applied to aduplex or multiple tee fitting, to afford a multiple or twin arrangementof girders in a horizontal plane. Fig. 10, is a detail side elevationillustrating the assemblage of a single and' duplex fitting of the elltype upon a column to provide a duplex or multiple arrangement ofgirders in a vertical plane.

Similar numerals of reference indicate like parts in one or more lateralbranches 2, in angular relation to said main shell 1,an'd adapted toafford support and attachment for the adjacent ends of one or moregirders or like members having angular relation to the aforesaid columnand carried thereby. In Fig. 10, a por tion 3 of the supporting columnor post is shown proof Letters Patent. Application filed December27,1906. Serial No. 349.683.

videdwith the present fittings for supporting adjacent ends 4, of aseries of horizontalgirders ofa building structure. w

In one part of the present invention the circular wall ot thebody'p'o'rtioiior main shell 1, or the fitting is.) formed withanopening 5 along its length; and'in cone? ,Yr iection therewith,opposed'marginalears or flanges 6 :areprovided 'onfthe exterior of saidshell! adjacent to .s'aid' opening Such ears or fiflanges are formedwith; for the passage of ordinary clamping bolts by means of which said.ears or fiang'es are drawn together to cause a contraction in thediameter of the stantial attachment thereof to the post or column; and

in a manner which permits of an accurate relation of the parts beingreadily attained. When desired .transverse bolt holes 8 may be formed inthe shell ahd'girder etc. for the passage 0f bolts to fixedly securethe'fitting in place on the column, feftc. against an endwise movement'or slip thereon. cfih'e scope of the part of the invention embraces theiorrnation'oi the shell 1 with more than one opening 5 and accompanyingears" or flanges .6; practical ei sperience has howevershown that 'veryeffective results are attained with a single opening 5 and accompanyingears or fla'nges'fi, as shown in the drawings, and such form offittingis accordingly'pre- 'ierred for general application. In another part ofthe present invention the lateral branchesZ, oi the fitting are made ofa U or stirrup shape as shown with a view to admit 'of the readyintroduction-ofqthe horizontal such construction, the side Webs oisuchbranches are provided withalined bolt holes!) for thebpassage of ordinary bolts; which bolts pass through said bolt .holes and'throughcorresponding transverse bolt holes in the end of the girder occupyingthe socket provided by the shell and in consequence effect aver-ystrpngand subs5 tubular girders, etcl intoplace; and'in connection withabove described construction, and as fully set forth in 7 my companionapplications serial Numbers 349,682 and 349,684.

In,the preferred, construction of the fittings shown in Figs. 1, 3, 4,5,6,7, and 8, a branch 5 of the heretofore described opening 5 in theshell 1, will be formed cen;

trally in the semi-circular wall of the branch 2't0 afford additionalmeans-for clamping and holding the end of -the girder in place, and insuch construction the op posed ears or flanges 6 with their clampingbolt as here-- tofore described, will act to contract the parts of saidbranch or stirrupnpon the girder. It'is however within the province ofthis part of the invention to arrange" the opening 5 with itsbeforedescrihed accessories at a point removed from said branchesor stirrups,as illustrated in Fig. 9,'When circumstances or the judgment of theconstructor may so-direct.

In another part of thepresent invention the fitting is provided withduplicate or twin Lateral branches 2 Cit and 2 of counterpar bolt holeson said transverse plane the an t constrru-tion. tothat already de sribed. and as illustrated in Figs. 7. 25 and 9 with a view to receivepairs of girders in parallel and horizontal relation, for the class ol'training constructions requiring extra lateral strength in the girders.as more particularly set forth in my companion application Serial No.349.684 before rel'erred to; And with such construction still greaterlateral strength can be readily attained by placing one oi the firstdescribed littings innnediately above or below the duplex-fitting -lastde scribed, and attaching thereto a single girder as illns trated inFig. 1G.

in the preferred construction of the various fittings shown anddescribed. the circular bores oi the shell and lateral branches 2. openone into the other so as permit the fitting to be placed along thelength of a colunin, girder or other framing member, as circnnr stancesor the judgment oi the constructor may direct.

Minor modifications oi the fittings may be made l'rqin that shown in thedrawings, so as to adapt the same to diiierent positions in the buildingi'raine, and'can' he lent to the judgment oi the constructor in applyingthe present fitting to the particular use which requires suchinodification. I

Having thus fully described my said invention what I claim as new anddesire to secure by Letters Patent isz- i. A fitting for connectingtubular lvu nether. the same t'dxnprising'a main shell. and one or moreintegrally formed lateral lirzlnchps. of a U shape the side walls ofwhich extend above a transverse plane intersecting the ,longitudinalaxis of saidbranches the said shell having; an opening" along its lengthand provided with lugs or cars on its exterior for the pass :e of aclamping," bolt, substantially as set forliln Y l.
